Redirect Issue

application_controller.rb

class ApplicationController < ActionController::Base
  protect_from_forgery
  
  rescue_from CanCan::AccessDenied do |exception|
    flash[:alert] = exception.message
    redirect_to root_url
  end

  protected

  def stored_location_for(resource)
    if current_user && (current_user.role?("admin") || current_user.role?("moderator"))
      return admin_index_path    # Make sure this route exists in your app!
    end
    super(resource) 
  end

end

user.rb

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :token_authenticatable, :confirmable, :lockable and :timeoutable
  devise :database_authenticatable, :registerable, 
         :recoverable, :rememberable, :trackable, :validatable

  # New Sign Ups
  attr_accessible :email, :password, :password_confirmation, :remember_me, :username
  has_and_belongs_to_many :roles
  has_many :articles
  
  # ensures usernames are unique and included in sign-up
  validates :username, :presence => true, :uniqueness => true
  
  def role?(role)
   return !!self.roles.find_by_name(role.to_s)
  end
  
  before_create :setup_role
  private
  def setup_role
    if self.role_ids.empty?
      self.role_ids = [3]
    end
  end
end

Hmmm... puzzling. Looks like the if block is not being reached at all (ie: it's not recognising the user as an admin nor moderator). Please could you start a rails console (rails c) and type in the following and send me the output:

u = User.find(admin_user_id)    # admin_user_id should be the ID of the user you are logging in as
u.role? "admin"
u.role? "moderator"

Okay, now this really is puzzling...

I am neither an Admin, Moderator or Member but I have sign In and full editing/delete permissions.

Other users who are members don't have these permissions on the website.

irb(main):007:0> u=User.find(1)

models/ability.rb

class Ability
include CanCan::Ability

def initialize(user)
user ||= User.new # guest user

if user.role? :Admin
  can :manage, :all
  can :publish, Article
elsif user.role? :Moderator
  can :read, [Article, Comment]
  can [:edit, :update], Comment
elsif user.role? :Member
   can :read, :all
   can :create, [Article, Comment]
   can [:edit, :update], Comment
end

end
end

/models/user.rb

def role?(role)
return !!self.roles.find_by_name(role.to_s)
end

default role for new users as authors

before_create :setup_role
private
def setup_role
if self.role_ids.empty?
self.role_ids = [3]
end
end

In Rails Console, try:

u = User.find(admin_user_id)    # admin_user_id should be the ID of the user you are logging in as
u.role? :Admin
u.role? :Moderator

Also, what database are you using? MySQL? Postgres?

Good spot!

I'm using SQLite3 in Aptana Studio 3 dev.env

irb(main):002:0> u.role? :Admin
=> true
irb(main):003:0> u.role? :Moderator
=> false
irb(main):004:0>

Ah ha! Then it's to do with the case sensitivity... d'oh!

Does it all work as you'd like now?

If so, please do mark up my answer on StackOverflow and also mark it as the correct answer :)

Legend... well done, it works perfectly and I tested it with both the Admin and Member!

If you were up for a challenge, I just need to get this Atom feed working and the project is finished!?

http://stackoverflow.com/questions/6179512/rails-3-help-with-atom-feed

Ace!

Did my answer here - http://stackoverflow.com/questions/6175928/rails-3-atom-feed-problem/6176888#6176888 - not help with this problem?

I've provided an answer for: http://stackoverflow.com/questions/6179512/rails-3-help-with-atom-feed

Thanks - I added your other suggestion alright, but still having an issue with it!

You know, I've followed 4 different tutorials from this ATOM feed and none of them have worked for me... might start blogging when this is finished lol
